Bug How to add all values from a Text array to a float variable

So I have a Text[] and a float and I was wondering how I can add each of Text values to float and then set the text to that.

Code (CSharp):

1. public class TotalMoney : MonoBehaviour
2. {
3.     public Text textt;
4.     public Text[] moneyFields;
5.     public float totalMoney;
6.  
7.     void Update()
8.     {
9.         textt.text = "Total: " + totalMoney;
10.     }
11. }

 

The concept is very simple:

* iterate (loop) over the array
* each Text in the array has a .text which is a string
* convert the string to a float
* add the float to a running total

Code (CSharp):

1. totalMoney = 0f;
2. foreach (Text field in moneyFields)
3. {
4.     string displayed = field.text;
5.     float amount = float.Parse(displayed);
6.     totalMoney += amount;
7. }

There are gotchas, though.

* what if the string doesn't convert to a float, because of punctuation or it's empty?
* what if your user supplied strings like "€34,12" because that's how their country does it?
* how do you deal with rounding errors or unexpectedly huge or tiny values?

Using strings as a way of storing and working with numbers is a bad approach. You should be holding an array of floats, and converting them to strings for display purposes only.

 

what do I put on strFloatValue?

 

Sorry, quick mistake there. I meant

displayed
